I’m currently testing PDoA using the QM33120WEVB and QM33110WEVB modules, each connected to an nRF52840-DK board.
The QM33120WEVB is equipped with a Julie antenna(JL359), and I’m curious about the exact physical distance between the antennas when using these modules for ranging.
Does anyone happen to have detailed mechanical specs or reference measurements for the Julie antenna placement on the QM33120WEVB?
Any insights or official documentation references would be greatly appreciated. Thanks in advance!
The exact details about the Jolie antenna are confidential and if you are looking for more details on this, I would recommend to contact your local sales representative to get more information using the “Find your local sales contact” tool here.
In terms of guidelines for AoA designs, we have an application note, APH511, found on our page here which discusses the antenna element spacing in section 3.
I’m currently conducting research using the QM33120WEVB, and in order to analyze the phase difference accurately, I need to know the exact antenna spacing. While I could measure it manually, I would prefer to obtain the official value to ensure precision and completeness in my research.
Would it be possible to confirm the exact antenna spacing for the QM33120WEVB? I would really appreciate your help.
